 border of the hock (Fig. 50). Thickenings or enlargements in 

 this region may involve a variety of structures. Thickening of

 that extends from the posterior border of the bone that forms 

 the summit of the hock to the external splint bone, and acts as a 

 stay for the point of the hock, is the structure usually involved 

 in curb.
